Snow – almost everyone likes it, right? The real question is, ‘just how much do you know about snow?’ Have you ever wondered what makes up snow? Why is snow white? What’s the shape of a snowflake? What is a snowstorm and a blizzard? In this article on Snow facts, we are going to learn a multitude of things about snow that you might need for your school homework. So, without wasting time any further, let us begin with our facts list…
Snow Facts: 1-5 | What really is snow?
1. Snow is nothing more than ice in form of very tiny crystals. These tiny crystals are called snow crystals. Precipitation of snow is called snowfall.
2. Just how these snow crystals are formed totally depends on the atmospheric conditions that are present at the time of formation of crystals and what happens to those crystals as they precipitate or fall to the ground.
3. Snow or snow crystals are formed inside the clouds. When the cloud temperature falls to extremely low levels, the water vapors in the cloud freeze forming very tiny ice crystals or snow crystals.
4. During snowfall (precipitation of the tiny ice crystals or snow crystals), the snow may come down in different forms. Simply put, snow crystals be of different types.
5. There are essentially 4 different types of snow. They are:

6. What are snowflakes? A single ice crystal is known as a snowflake. This singular ice crystal may actually grow big enough to fall in form of precipitation. However, a snowflake may also be formed through clubbing of several ice crystals.
7. A snowflake is always formed around dust particles present in supersaturated air masses. These dust particles attract droplets of water that are present in supercooled state. These water vapors then freeze into crystalline form.
8. These crystals can then grow by collecting water vapor on themselves. Because of extreme abundance of water vapors in clouds, the crystals thus formed can grow up to several hundreds of millimeters or micrometers.
9. These snowflakes that are formed can then move through various zones of humidity and temperature in the atmosphere, resulting in formation of complex shapes.
10. Snowflakes can depict a six-fold radial symmetry. This happens because the ice’s cystalline structure is six-fold. The six arms of a snowflake are known as dendrites. These dendrites then grow individually. Each dendrite can then grow arms, which too grow independently.
